Latinx students’ experiences with college access and preparation at college preparatory charter schools     

Melissa A. Martinez  Desireé Vega  Jocabed Marquez 《Journal of Latinos & Education》2019,18(1):28-41

Charter schools that target underserved communities, including Latinxs, have proliferated in the U.S., claiming a unique, more autonomous and successful alternative to traditional public schools, often with a promise of increased postsecondary access and preparation. However, there is conflicting evidence regarding their effectiveness on academic outcomes, prompting additional research on charter schools. This study examined the college access and preparation experiences of 14 Latinxs attending college preparatory charter schools within one school system in Texas. Findings highlight how schools assisted students in preparing for college, but challenges in accessing college knowledge and assistance still existed, particularly for undocumented students.  相似文献   

AIDA: a methodology independent support tool for educational software authoring     

António José Mendes  Teresa Mendes 《Education and Information Technologies》1996,1(1):55-74

Many authoring tools have been proposed in an attempt to find more effective ways to face the challenge of developing educational software. However, most of them are reported to be restrictive, since they are strongly connected to a specific educational software development methodology. The AIDA (Ambiente Integrado para o Desenvolvimento de Aplicações educacionais) authoring environment was developed at the University of Coimbra having as its main objectives the support of most of the activities involved in authoring and making educational software development easier. The AIDA system is based on a design module, i.e. a prototyping tool allowing the creation of Windows-based software, including multimedia features. The system assists evaluation activities and it caters also for support on translation and cultural adaptation, as well as on the reutilization of educational materials. The use of the AIDA environment is illustrated by three small examples using different development methodologies.  相似文献   

Origins of individual differences in theory of mind: from nature to nurture?     

Hughes C  Jaffee SR  Happé F  Taylor A  Caspi A  Moffitt TE 《Child development》2005,76(2):356-370

In this study of the origins of individual differences in theory of mind (ToM), the Environmental Risk (E-Risk) Longitudinal Twin Study sample of 1,116 sixty-month-old twin pairs completed a comprehensive battery of ToM tasks. Individual differences in ToM were striking and strongly associated with verbal ability. Behavioral genetic models of the data showed that environmental factors explained the majority of the variance in ToM performance in this sample. Shared environmental influences on verbal ability had a common impact on ToM and explained more than half the phenotypic correlation between these two skills. Possible underlying proximal mechanisms are discussed, including maternal speech and mind-mindedness, sibling interactions, and peer influences.  相似文献

Zum Problem der Hochschulreform in Spanien: Einige Ausgewählte Daten     

Val  José Cajide  Philipp  Rita Radl  Castro  Ana Porto 《International Review of Education/Internationale Zeitschrift für Erziehungswissenschaft/Revue internationale l'éducation》1998,44(5-6):583-596

Over the past ten years there has been a sweeping reform of the courses taught and qualifications awarded by Spanish universities. For that reason, an investigation was launched in 1996–97 at the University of Santiago de Compostela (in Northwest Spain) into the teaching, research and management entailed in four new degree courses: physics (years one to four), agricultural engineering (first and second years), agricultural food-processing technology (years one to three) and pharmacy. This article reports on students' opinions of the reforms in these courses, revealing dissatisfaction with facilities for practical course work, lack of connection with prospective employment, and a call for more information about courses.  相似文献   

Dynamic Transition Patterns in Acculturation Among Hispanic Adolescents

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, M_age (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed.  相似文献   

Interaction between cells in dielectrophoresis and electrorotation experiments     

Miguel Sancho  Genoveva Martínez  Sagrario Mu?oz  José L. Sebastián  Ronald Pethig 《Biomicrofluidics》2010,4(2)

Progress in microelectrode-based technologies has facilitated the development of sophisticated methods for manipulating and separating cells, bacteria, and other bioparticles. For many of these various applications, the theoretical modeling of the electrical response of compartmentalized particles to an external field is important. In this paper we address the analysis of the interaction between cells immersed in rf fields. We use an integral formulation of the problem derived from a consideration of the charge densities induced at the interfaces of the particle compartments. The numerical solution by a boundary element technique allows characterization of their dielectric properties. Experimental validation of this theoretical model is obtained by investigating two effects: (1) The influence that dipolar “pearl chaining” has on the dielectrophoretic behavior of human T lymphocytes and (2) the frequency variation of the spin and orbital torques of approaching insulinoma β-cells in a rotating field.  相似文献   

Non-centralized control for flow-based distribution networks: A game-theoretical insight     

Julian Barreiro-Gomez  Carlos Ocampo-Martinez  Nicanor Quijano  José M. Maestre 《Journal of The Franklin Institute》2017,354(14):5771-5796

This paper solves a data-driven control problem for a flow-based distribution network with two objectives: a resource allocation and a fair distribution of costs. These objectives represent both cooperation and competition directions. It is proposed a solution that combines either a centralized or distributed cooperative game approach using the Shapley value to determine a proper partitioning of the system and a fair communication cost distribution. On the other hand, a decentralized non-cooperative game approach computing the Nash equilibrium is used to achieve the control objective of the resource allocation under a non-complete information topology. Furthermore, an invariant-set property is presented and the closed-loop system stability is analyzed for the non-cooperative game approach. Another contribution regarding the cooperative game approach is an alternative way to compute the Shapley value for the proposed specific characteristic function. Unlike the classical cooperative-games approach, which has a limited application due to the combinatorial explosion issues, the alternative method allows calculating the Shapley value in polynomial time and hence can be applied to large-scale problems.  相似文献   

Faculty attitudes and training needs to respond the new European Higher Education challenges     

María José Fernández Díaz  Rafael Carballo Santaolalla  Arturo Galán González 《Higher Education》2010,60(1):101-118

The main objective of the Bologna Process is to create a “European space” for higher education that allows for comparability, compatibility, and coherence between the existing systems of higher education across Europe. This objective is commonly known as the European higher education area (EHEA). The creation of the EHEA is a new and specific challenge for higher education in Europe, one that depends upon improved faculty development and training across Europe. The integration of Spain and other European countries into European higher education more generally entails these challenges. In order for necessary changes in faculty development and training to take place, university managers and policy makers must account for designing training plans, as well the knowledge, attitudes and needs of faculty members. This investigation was undertaken with these themes in mind. Conducted in Madrid, Spain, it included 257 professors from ten different schools of the Universidad Complutense de Madrid. The aim of the investigation was to understand faculty knowledge and attitudes about changes in higher education in Europe. Moreover, with an eye to helping faculty members cope with the change that is accompanying the creation of EHEA, the investigators sought to understand the importance that faculty members place upon professional development and how current approaches to professional development at the university level could be improved. The results indicate a degree of ignorance regarding changes in European higher education as well as a feeling of resistance on the part of many faculty members. While many faculty members consider knowledge of change processes and adaptability to be important qualities, faculty responses also indicate a clear need for guidance if they are going to integrate new learning models and adequate coping strategies into their work in higher education.  相似文献   

Career coping styles: differences in career attitudes among secondary school students     

Isabel N. Janeiro  José Ferreira Marques 《International Journal for Educational and Vocational Guidance》2010,10(1):35-48

The types of difficulties associated with career attitudes were studied using Super’s model of career maturity (1990) in a group of 620 Portuguese students from grades 9 and 12. A cluster analysis identified four styles with different patterns of association between time perspective, attributional beliefs, self-esteem and career attitudes. The adaptive style showed more committed career attitudes, and the other three styles—superficial, insecure and pessimistic—showed lower levels of career maturity. Implications for career counselling are further discussed.  相似文献
